Comprehensive Ergonomics Guide for Office Workers

Office workers face unique ergonomic challenges that can lead to musculoskeletal disorders. Understanding and implementing proper ergonomics can prevent pain, improve productivity, and enhance overall wellbeing.

The Office Ergonomics Challenge

Common Issues

Office workers frequently experience:

• Neck and shoulder pain
• Lower back discomfort
• Wrist and hand problems (carpal tunnel syndrome)
• Eye strain and headaches
• Hip and leg issues from prolonged sitting

Risk Factors

Prolonged Static Postures:

• Sitting for extended periods
• Fixed head/neck positions
• Sustained arm positions
• Limited movement

Repetitive Motions:

• Typing and mousing
• Phone use
• Document handling
• Repetitive clicking

Poor Workstation Setup:

• Incorrect monitor height
• Improper chair adjustment
• Inadequate keyboard/mouse placement
• Poor lighting
• Cluttered workspace

Workstation Ergonomics

Monitor Setup

Height:

• Top of screen at or slightly below eye level
• Viewing angle 10-20 degrees below horizontal
• Prevents neck strain

Distance:

• 20-26 inches from eyes (arm's length)
• Adjust based on vision and screen size
• Larger screens may need greater distance

Position:

• Directly in front of user
• Perpendicular to windows (reduce glare)
• Tilt slightly back (10-20 degrees)

Multiple Monitors:

• Primary monitor directly ahead
• Secondary monitor at angle
• Both at same height
• Consider curved arrangement

Keyboard and Mouse

Keyboard Position:

• Directly in front of user
• At elbow height when seated
• Slight negative tilt or flat
• Close to body (avoid reaching)

Mouse Placement:

• Same height as keyboard
• Close to keyboard
• Within easy reach
• Consider alternative input devices

Technique:

• Wrists neutral (not bent up/down or side to side)
• Elbows at 90-110 degrees
• Shoulders relaxed
• Light touch on keys
• Whole arm movement for mouse

Accessories:

• Keyboard tray for proper height
• Wrist rest for breaks (not while typing)
• Ergonomic keyboard (split, curved)
• Vertical or trackball mouse

Posture and Movement

Proper Sitting Posture

Neutral Spine:

• Maintain natural curves

• Wrists neutral

Lower Body:

• Hips back in chair
• Thighs parallel to floor
• Feet flat on floor or footrest
• Weight evenly distributed

Movement Strategies

Micro-Breaks:

• Every 20-30 minutes
• 30-60 seconds
• Look away from screen
• Stretch or change position
• Stand or walk briefly

Macro-Breaks:

• Every 60-90 minutes
• 5-10 minutes
• Leave workstation
